Tomcat 5.5 and JSTL

How to use JSTL tag library with Tomcat 5.5 and Maven:

1. Add Maven dependencies:

   <dependency>
       <groupId>javax.servlet</groupId>
       <artifactId>jstl</artifactId>
       <version>1.1.2</version>
   </dependency>
   <dependency>
       <groupId>taglibs</groupId>
       <artifactId>standard</artifactId>
       <version>1.1.2</version>
   </dependency>
   

2. Make sure you use at least Servlet version 2.4 in web.xml:
   

   <?xml version="1.0" encoding="UTF-8"?>
   <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
               http://java.sun.com/xml/ns/j2ee
               http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
   version="2.4">
   
   </web-app>
   

3. Add declaration in your JSP file:
   

   <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
   

4. Use JSTL tags:
   

   <c:set var="conditionValue" value="${true}"/>
   <c:if test="${conditionValue}">
   YES
   <c:if>
